ABSTRACT:
A surgical instrument for removing the cataractous nucleus from the eye. The instrument consists of a proximal handle and plunger. The plunger also acts as a screw-drive for an auger located at the distal end of the instrument. The screw-drive plunger is advanced exposing a nucleus encasing basket at the distal end of the instrument. The nucleus is completely encased in the distal basket and slowly ground up by the auger, removing the nucleus from the eye in its entirety. The use of unique internal gearing between the auger and encasing element results in a safe, efficient, controllable evacuation of the nucleus from the eye.
